The draft inducer is a small motorized fan that turns on before the burners ignite. Its purpose is to pull combustion air through the heat exchanger and expel toxic exhaust gases safely out the flue vent. A pressure switch verifies that this draft is established; if the inducer motor fails or the vent is blocked, the furnace will lock out as a safety precaution.
What Homeowners Say About Our Service in Sunnyvale
"We had an annoying buzzing sound coming from our furnace control board whenever heat was called. The technician diagnosed a failing 24V transformer and relay contactor in our Sunnyvale, California home. Replaced both parts quickly at a very fair rate. Couldn't ask for a smoother experience."
"Exceptional heating service in Sunnyvale, California. Our high-efficiency condensing furnace had water pooling around the bottom and shut down on error code 33. The technician cleaned a clogged condensate trap, flushed the drain lines, and tested combustion efficiency. Friendly, tidy, and very skilled."
"Our furnace was short-cycling—turning on for three minutes then kicking off while the house stayed freezing. The tech discovered our high-limit switch was failing and our flue vent had partial blockage. He cleared the vent and installed an OEM limit switch in our Sunnyvale, California residence. House is toasty warm again."
